You have a Torsen LSD, not a clutch type. That being said, I'm not sure the Motul stuff would actually hurt it. I seem to remember reading though that oils made for the clutch type have a higher friction coefficient, or different lubricity, or something like that and I'm not sure that's exactly what you'd want with a Torsen.

I know some people prefer Neo over Redline in their differential, but I don't think either is the cause of any real complaints. I've got Redline in mine and it works fine. So, if you can't get Neo, why not pick up some of the generally available Redline 75w-90 ?

I just re-read your post again. If it's a choice between 1 and 2, go with 2 definitely.

I agree. the gear300 looks like an excellent choice. Just don't put it in your tranny

Thanx Jconn!! I was told that the LSD Motul Oil is used by the Porsche for example.
I think that I will be ok with the gear300 on my differential

No, I'm sorry I misread that the gear300 looks fine for tranny use. It's the first one that shouldn't be used in any synchromesh tranny.
